  2. Chloromethane - Wikipedia

    en.wikipedia.org/wiki/Chloromethane

    Chloromethane, also called methyl chloride, Refrigerant-40, R-40 or HCC 40, is an organic compound with the chemical formula CH 3 Cl.One of the haloalkanes, it is a colorless, sweet-smelling, flammable gas.

  3. Chemical polarity - Wikipedia

    en.wikipedia.org/wiki/Chemical_polarity

    Note that the dipole moments drawn in this diagram represent the shift of the valence electrons as the origin of the charge, which is opposite the direction of the actual electric dipole moment. The bond dipole moment [5] uses the idea of electric dipole moment to measure the polarity of a chemical bond within a molecule. It occurs whenever ...

  4. m-Xylene - Wikipedia

    en.wikipedia.org/wiki/M-Xylene

    m-Xylene (meta-xylene) is an aromatic hydrocarbon.It is one of the three isomers of dimethylbenzene known collectively as xylenes.The m-stands for meta-, indicating that the two methyl groups in m-xylene occupy positions 1 and 3 on a benzene ring.

  5. Polarizability - Wikipedia

    en.wikipedia.org/wiki/Polarizability

    The polarizability of an atom or molecule is defined as the ratio of its induced dipole moment to the local electric field; in a crystalline solid, one considers the dipole moment per unit cell. [1] Note that the local electric field seen by a molecule is generally different from the macroscopic electric field that would be measured externally.

  6. Rotational spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Rotational_spectroscopy

    The extent of splitting depends on the square of the electric field strength and the square of the dipole moment of the molecule. [30] In principle this provides a means to determine the value of the molecular dipole moment with high precision. Examples include carbonyl sulfide, OCS, with μ = 0.71521 ± 0.00020 debye.

  7. Partial charge - Wikipedia

    en.wikipedia.org/wiki/Partial_charge

    In atomic physics, a partial charge (or net atomic charge) is a non-integer charge value when measured in elementary charge units. It is represented by the Greek lowercase delta (𝛿), namely 𝛿− or 𝛿+. Partial charges are created due to the asymmetric distribution of electrons in chemical bonds.

  8. Dipole moment - Wikipedia

    en.wikipedia.org/wiki/Dipole_moment

    Transition dipole moment, the electrical dipole moment in quantum mechanics; Molecular dipole moment, the electric dipole moment of a molecule. Bond dipole moment, the measure of polarity of a chemical bond; Electron electric dipole moment, the measure of the charge distribution within an electron; Magnetic dipole moment, the measure of the ...

    Deoxy-hemoglobin is generally accepted to be a complex of iron in the +2 oxidation state, that is a d 6 system with a high-spin magnetic moment near to the spin-only value of 4.9 μ B. It was proposed that the iron is oxidized and the oxygen reduced to superoxide.
